Omega2 Posted May 11, 2005 Share Posted May 11, 2005 Tonight I was on a hike and wanted to waymark a location. I was about to switch on the averaging to get a better fix, when I saw that the estimated accuracy (estimated error?) was 7.6 feet. This was rather stunning as I'm more used to seeing an accuracy of 20 to 40 feet. I switched to the satellite page and found capital "D"s showing, indicating WAAS/EGNOS error corrections. "New" satellites 44 and 39 were shown. There have been a few occasions when I have seen error correction for a few minutes at a time, but this stayed consistent for at least an hour. I assume that one of these satellites 44 and 39 is the geo-stationary east atlantic InMarSat. As far as I know, that is received in Scotland, Ireland and parts of Wales and Cornwall but the further south you go, the less coverage you get. The other InMarSat transmitting the EGNOS signal is over the Indian Ocean and should be completely out of my range. I live in north east England in Teesside. So the questions are: Which areas of the UK regularly receive GPS error corrections, and where are satellites 44 and 39? Quote Link to comment
